6 Unpacking, installation and commissioning
6.1 Place of installation, place of use
The balance is constructed in such a way that reliable weighing results can be achieved
under normal application conditions.
By selecting the correct location for your balance, you will be able to work quickly and pre-
cisely.
Therefore please observe the following at the place of installation:
-
Place the balance on a firm, level surface;
-
Avoid extreme heat as well as temperature fluctuation caused by installing next to a
radiator or in the direct sunlight;
-
Protect the balance against direct draughts due to open windows and doors;
-
Avoid jarring during weighing;
-
Protect the balance against high humidity, vapours and dust;
-
Do not expose the device to extreme dampness for longer periods of time. Inad-
missible bedewing (condensation of air moisture on the device) can occur if a cold
device is taken into a significantly warmer environment. In this case, please accli-
matise the device for approx. 2 hours at room temperature after it has been discon-
nected from the mains.
-
Avoid static charging of the material to be weighed, weighing container and wind-
shield.
Major display deviations (incorrect weighing results) are possible if electromagnetic fields
occur as well as due to static charging and instable power supply. It is then necessary to
change the location.
6.2 Unpacking
Carefully remove the balance from its packaging, remove the plastic wrapping and posi-
tion the balance in its intended working location.
6.2.1 Installation
Install the balance in such a fashion that the weighing plate is absolutely horizontally.
6.3 Mains supply
Electric power supply is by means of the external mains supply circuit. The printed voltage
level must comply with the local voltage.
Only use original KERN mains supply circuits. The use of other makes is subject to ap-
proval by Kern.
